Symptoms

Bell's palsy symptoms may come on suddenly or develop over a few days. Initial symptoms may include:

Pain behind the ear that is followed by weakness and paralysis of the face

Ringing sound in the ears

Slight hearing impairment

Slight increase in sensitivity to sound on the affected side

Symptoms of advanced Bell's palsy may include:

Facial weakness or paralysis, most often on one side

Numbness just before the weakness starts

Drooping corner of the mouth

Drooling

Decreased tearing

Inability to close an eye, which can lead to:

Dry, red eyes

Ulcers forming on the eye

Infection

Problems with taste on one side

Sound sensitivity in one ear

Earache

Slurred speech

Late complications can occur 3-4 months after onset and can include:

Long-lasting tightening of the facial muscles

Tearing from eye while chewing

Symptoms will often go away on their own within a few weeks. Bell's palsy
may resolve after a few months in many people. In some cases, some symptoms of Bell's palsy may never go away. The recovery rate decreases with increasing age.

Diagnosis

You will be asked about your symptoms and medical history. A physical exam will be done. The diagnosis is usually made with just the physical exam. Information from your health and medical history may be used to determine a potential cause.

Concern about infections or other specific causes may require further testing.

Treatment

For most, treatment is not needed. You may be referred to a specialist if you have eye problems, if your symptoms worsen, or if your recovery takes longer than expected.

If an underlying cause of the Bell's palsy is known, it may be treated. Treatment for underlying conditions may include medication or surgery.

Medication

Your doctor may prescribe
corticosteroids if your symptoms have been present for a short time. This is a medication that can decrease swelling and pain.

Antiviral medications along with corticosteroids may be advised. There is no evidence that antiviral medication alone has any benefit.

Self-care

If the paralysis includes your eyelid, you may need to protect your eye. This may include:

Lubricant or eye drops

Covering and taping your eye closed at night

An eye patch to keep the eye closed

Massaging the weakened facial muscles may also help.

Therapy

Physical therapy may be advised to improve function.

Symptoms can be distressing. Counseling can help you manage emotional issues and make appropriate adjustments.
